Microsoft Edge Pinned on Taskbar Opening Another Windowīefore moving on with the solutions to stop Edge from opening new Windows, make sure that the setting of Combine Taskbar Buttons in the system’s Settings is set to ‘ Always, Hide Labels’. The behavior is usually noted after an update of the Edge browser.

Every new instance of Edge will stack up on the new window, not on the pinned icon. The issue arises when the user pins the Edge to his taskbar and uses the pinned icon to launch Edge but Edge launches as another window (not stacked up on the pinned icon). Moreover, more than one installation of Edge (like Canary or Dev) or more than one Edge user profiles may also cause the issue at hand. You may see more than one Edge icon on the taskbar if the installation of Microsoft Edge is outdated or corrupt.
